USB BIOS Flashback

USB BIOS Flashback allows you to easily update the BIOS without entering the existing BIOS or operating system. Simply insert a USB storage device to the USB port (the USB port hole marked in green on the I/O shield) then press the USB BIOS Flashback button for three seconds to automatically update the BIOS.

To use USB BIOS Flashback:

1.Place the bundled support DVD to the optical drive and install the USB BIOS Flashback Wizard. Follow the onscreen instructions to complete the installation.

2.Insert the USB storage device to the USB Flashback port.

• We recommend you to use a USB 2.0 storage device to save the latest BIOS version for better compatibility and stability.

Refer to section 2.3.1 Rear I/O connection for the location of the USB port that supports USB BIOS Flashback.

3.Launch the USB BIOS Flashback Wizard to automatically download the latest BIOS version.

4.Shut down your computer.

5.press the BIOS Flashback button for three seconds until the Flashback LED blinks three times, indicating that the BIOS Flashback function is enabled.

For more BIOS update utilities in BIOS setup, refer to the section 3.11 Updating BIOS in Chapter 3.

Do not unplug portable disk, power system, or press the CLR_CMOS button while

BIOS update is ongoing, otherwise update will be interrupted. In case of interruption, please follow the steps again.

If the light flashes for five seconds and turns into a solid light, this means that the BIOS Flashback is not operating properly. This may be caused by improper installation of the USB storage device and filename/file format error. If this scenario happens, please restart the system to turn off the light.

Updating BIOS may have risks. If the BIOS program is damaged during the process and results to the system’s failure to boot up, please contact your local ASUS Service Center.
